there's obviously something I am missing...
$ cap test2 deploy:code
./config/deploy.rb:297:in `lambda': tried to create Proc object without a block
(ArgumentError)
from ./config/deploy.rb:297:in `load'
and line 297 is the first line of this 'set' command...
set :user, lambda do
my_user = Capistrano::CLI.ui.ask("Your SSH User name [#{`user`.strip}]: ");
if my_user.empty?
`user`.strip
else
my_user
end
end
(though I suspect that `user` is a problem, I didn't get that far)
Thanks
